Vanchiro is better known by his alias, Jeffrey Gamblero. He is well-known to Nets players and fans alike, and is often shown dancing on the Barclays Center Jumbotron, clad in eye-catching neon apparel.

Brett Yormack, CEO of the Brooklyn Nets and Barclays Center, released a statement Sunday evening:

On behalf of ownership and the entire organization, I am terribly saddened to learn about Jeffrey’s death. A proud Brooklynite, Jeffrey was a passionate Nets fan and one of our most visible and loyal supporters. I was delighted that he joined the team on our trip to London last season and always enjoyed his enthusiasm while dancing and cheering during Nets games at Barclays Center. The entire organization expresses our deepest condolences to his family and friends. He will be missed.
